Defender Game Racer Classic (Mortal Kombat X)

Hey gamers!
Decided to get acquainted with the world of gamepads, and racing\of simracing there is a wheel, for fighting games decided to take a separate controller. The choice fell on the secondary market on the device Defender Game Racer Classic. And here's the question:
1) whether this controller is Compatible with MK X\XL?
2) even whether to bother with rudders that one steering wheel is suitable for a particular game and the other not?
3) Again, is it worth it to purposefully look for this model as Defender Game Racer Classic ( 6 buttons on the right, good cross for Veit, poseredine button of nowhere, and the back side of the trigger ) or you can buy a standard gamepad as a xbox360 from\PS?
